Gel permeation chromatographic determination of activation rate constants in nitroxide‐controlled free radical polymerization, 2. Analysis of evolution of polydispersities

摘要

AbstractThe dissociation rate constantkdof the PS‐TEMPO adduct, where PS is polystyrene and TEMPO is 2,2,6,6‐tetramethylpiperidin‐1‐oxyl, was determined by the gel permeation chromatographic tracing of the evolution of polydispersities at an early stage of styrene polymerization with a model PS‐TEMPO adduct as initiator. The results agree with those obtained by the direct method
